Base of Preference (BOP)

This program authorizes a BOP for first-term airmen in conjunction with the Career Airman Reenlistment Reservation
System (CAREERS) retraining, or an in-place BOP for career airmen or first-term airmen not retraining under CAREERS.

First-term airmen are afforded the opportunity to apply for a BOP in conjunction with CAREERS retraining. Career
airmen may submit an in-place BOP application after completing three years, five months on station. First-term
airmen not retraining under CAREERS may also apply after completing 17 months on station. (Note: consecutive in-place
BOPs are not authorized.)
